I save my work a lot due to the fact that I still can't trust Fusion 360 to remain stable for very long.
Sometimes I just want to save without naming or confirming anything. I could let Autosave do that for me, but I can only set Autosave to save every 15 minutes or more. I consider it a good day if Fusion 360 stays crash free for more than 10 minutes.
Even if I could set Autosave to save every 60 seconds, I'd still want to be able to simply press Cmd+S (or CTRL+S) and continue without being taken out of my flow to confirm the save.
What motived me to suggest the idea? I pressed Cmd+S and as I was moving the mouse to the confirm button, Fusion 360 crashed.
